En el presente tratamiento se definen los caracteres morfológicos del grupo y se incluye una clave para identificar las especies, descripciones, ilustraciones, fotografías y mapas de distribución de las mismas. Se discuten las relaciones de Eriantha con taxones afines de Paspalum. Finalmente, se designa un lectótipo para Paspalum erianthum Nees var. strictum Döll. /// Eriantha is an American group of Paspalum with five species distributed from Mexico in North America to Brazil, Bolivia, Paraguay, Argentina, and Uruguay: Paspalum ammodes, P. erianthoides, P. erianthum, P. guttatum, and P. paucifolium.
